Running NPM scripts

Are you sick of typing ./node_modules/.bin/eslint again and again? Yeah, me too.

Windows: Tired of forgetting the quotation marks?

Let’s open up package.json and make a little change. See the "scripts" part?

  "scripts": {
    "test": "echo \"Error: no test specified\" && exit 1"
  },

Right now there’s one script - it’s supposed to run tests, but it looks like it does a pretty bad job of it. For now, let’s just add a new test called lint that runs eslint for us.

  "scripts": {
    "test": "echo \"Error: no test specified\" && exit 1",
    "lint": "eslint --fix graph.js"
  },

Windows: No more quotation marks for this one! You’re free!

Be sure to add a comma at the end of the test line!

We can now have eslint run by just typing npm run lint. npm knows that even though we just type eslint that it needs to go into node_modules/.bin and find the secret eslint hiding in there.

So: never again type ./node_modules/.bin/ for anything! If you need to run a tool, add it to scripts to make your life so much easier.

Now, let’s get back to our code!
